Terms from the users mental model of the task Buttons, sliders, and other widgets are not part of the task. Databases, engines, and IO devices are not part of the

I want to make a permanent copy of the image (of a goose) currently displayed. 1. I decided to save the image. 2. I right clicked on the image.
3. I clicked on the save button. 4. I clicked on the no button in warning window. 5. I moved mouse to the file name field. 6. I changed the file name.
7. I clicked on the save button. 8. I receive feedback that the task is complete. Example Assignment 1 Annoyance Description I was annoyed in step 4 that I was
allowed to try to save the image with a file name that already exists. I was annoyed in step 6 that I had to guess a file name that had not already been used. Example Assignment 1 Why I was annoyed I was annoyed by step 4 because the
system set me up to fail. The system could have determined that the file name was already used and given me different options that one that would fail. I was annoyed by step 6 because I was not provided enough information to choose a file name that was not already used. How to fix the annoyance
